The Windows 7 craze is barely over, and yet the internet is already buzzing with the next big thing from Microsoft: a project called Midori. The SD Times claims to have seen internal Microsoft documents detailing what Midori actually is, and they say it's the clean-break from Windows many of us have been waiting for. The SD Times article is heavy on the details, and quite technical, but luckily Ars Technica provides a more accessible summary of what Microsoft has in store for Midori.

there are many interesting aspects to Singularity that can't be found in Inferno, although they have many things in common.
but still - the way they will deploy Midori [running hosted as "cloud" computing enviroment -> later standalone] is, what Inferno should've been.
